Rated performance and conditions
Manufacturer peak claims depend on cache state, host and workload. Queue depth and test systems must match before performance can be compared; these figures do not establish a faster everyday drive.

Check the connection before the capacity. M.2 NVMe modules and 2.5-inch SATA drives are not interchangeable. Check the host’s protocol, slot or bay, power connection and clearance. Rated speeds use different test systems; we do not turn them into a speed score or overall winner.
